CPU consumption on the local machine is not correlated to bandwith on the internet, unless you are running one of the core routers. > Wow, some websites seem to be running massive amounts of code in the > background causing my machine to sit at 100% CPU for a minute or two until > it is finished.

I can't recommend what to do for IE, but FireFox has a wonderful add-on in NoScript that lets you control when and what is allowed to run on your machine. For example, a couple of my favorite technical sites starting hosting jumping, dancing, looping adds on their pages, I've disabled Flash and only enable it when I want to see what's presented. > Has anyone else noticed this general slowdown recently? Some ISPs are badly oversubscribed. A number of websites have suffered outages or "brownouts" lately due to overuse or denial-of-service attacks. But the Internet as a whole continues to get faster, and continues to outpace the growth in usage. Well-written AJAX transmits small amounts of data, and is more efficient than reloading the pages to display updates. Some badly-written pages are slower, and you should complain to their webmasters. Some software, like tracking software, contributes nothing to the user experience, while slowing down the loading of a page. You can examine what a page is loading with a FireFox add-on like FireBug or YSlow, and consider blocking the sites that are just dragging down the page load. -- Ted Roche Ted Roche & Associates, LLC http://www.tedroche.com _______________________________________________ Post Messages to: [email protected] Subscription Maintenance: http://leafe.com/mailman/listinfo/profox OT-free version of this list: http://leafe.com/mailman/listinfo/profoxtech Searchable Archive: http://leafe.com/archives/search/profox This message: http://leafe.com/archives/byMID/profox/[email protected] ** All postings, unless explicitly stated otherwise, are the opinions of the author, and do not constitute legal or medical advice.
